I'm going to comment on a recent statement by Mike Licona:
Third, the truth of Christianity is grounded in the historicity of Jesus’ resurrection rather than the inerrancy of the Bible. If Jesus rose from the dead, Christianity would still be true even if it were the case that some things in the Bible are not. In fact, because Jesus rose, Christianity was true in the period before any of the New Testament literature was written. So, how could an error in the Gospels nullify the truth of Christianity? This is not to say the Bible contains errors. It is to say that, since the truth of the Christian gospel does not hang on every word in the Bible being correct, the doctrine of biblical inerrancy is, at the very most, a secondary doctrine.
This position is only an echo of that articulated in 1893 by B. B. Warfield, regarded as the father of the doctrine of biblical inerrancy:
Let it not be said that thus we found the whole Christian system upon the doctrine of plenary inspiration. We found the whole Christian system on the doctrine of plenary inspiration as little as we found it upon the doctrine of angelic existences. Were there no such thing as inspiration, Christianity would be true, and all its essential doctrines would be credibly witnessed to us in the generally trustworthy reports of the teaching of our Lord and of His authoritative agents in founding the Church, preserved in the writings of the apostles and their first followers, and in the historical witness of the living Church. Inspiration is not the most fundamental of Christian doctrines, nor even the first thing we prove about the Scriptures. It is the last and crowning fact as to the Scriptures. These we first prove authentic, historically credible, generally trustworthy, before we prove them inspired. And the proof of their authenticity, credibility, general trustworthiness would give us a firm basis for Christianity prior to any knowledge on our part of their inspiration, and apart indeed from the existence of inspiration. Warfield, "The Real Problem of Inspiration."

i) I disagree with Warfield's methodology, for reasons I'll come to momentarily. But I'd also note that Warfield is using a different argument than Licona. Warfield didn't say:
Even though the Bible claims to be plenarily inspired, if the self-witness of Scripture were proven false, Christianity would still be true.
Warfield is speaking hypothetically. This is even clearer from a similar statement he made:
We may say that without a Bible we might have had Christ and all that he stands for to our souls. Let us not say that this might not have been possible. But neither let us for- get that, in point of fact, it is to the Bible that we owe it that we know Christ and are found in him. ‘‘The Inspiration of the Bible,’’ in Revelation and Inspiration, 72.
So Warfield is discussing a counterfactual scenario in which the Bible doesn't claim to be plenarily inspired in the first place. A counterfactual scenario in which there is no Bible. A possible world where Christianity is not a revealed religion. Where the knowledge of Christianity solely depends on collective memory.
That wouldn't be the same religion. It would be significantly similar to Christianity inasmuch as many of the key events would be the same, but it would be significantly dissimilar as well.
That is very different from Licona's argument that if, in the real world, Scripture was found to be errant in spite of Scripture's self-witness to the contrary, Christianity would still be true. Even if Licona's argument is a good argument, it's not the same argument as Warfield's. It's not the same position.
ii) It's true that inspiration and the Resurrection are two causally independent events. In that sense, the truth of the Resurrection is not contingent on the truth or falsity of inspiration. Hypothetically speaking, you could have many of the same redemptive events with or without an inspired record.
That, however, doesn't mean Christianity would still be true. Rather, that would mean Christianity is partially true.
For instance, imagine OT Judaism without the prophets. Imagine Judaism without Isaiah, Jeremiah, Ezekiel, Hosea, &c. You could still have many of the same events. The calling of Abraham could still be true. The Exodus could still be true. And so on and so forth. However, OT Judaism without the prophets would not be the same religion.
iii) In addition, Licona is erecting a false dichotomy between divine words and divine works. But when God raised up prophets, that's a divine event. Sending prophets to Israel is something God does as well as something God says. So we can't neatly separate the works of God from the words of God.
iv) To take another example: in Isa 40-48, one factor distinguishing the true God from false gods is that Yahweh says he's going to do something, then does it. Predictive prophecy is a fundamental element of OT theism. God does what he says he will do. God says what he will do before he does it.
If, however, God simply did things without announcing his intentions in advance, you'd only have half the religion. There's far more to Biblical theism than what God does. God is a God who foretells his actions, then fulfills what he foretells. Among other things, inspiration points to a God who knows and controls the future. God gives a word (to or through a prophet), then acts on his word. That's an essential component of Biblical theism. A God who makes promises, then makes good on his promises.
v) What about Warfield's argument? In addition to what Licona quoted, Warfield deploys variations on this same argument. For instance:
Inspiration, in its more exact sense, cannot come into the discussion until theism, the reality of revelation, the divine origin and character of the religion which they present, and the general trustworthiness of their presentation of it, have been already established. It is the crowing attribute of these sacred books, and is inconceivable and would not be affirmed if they were not previously believed to be the trustworthy records of a divinely given religion. Selected Shorter Writings, 2:632.
But certainly, before we draw it from the Scriptures, we must assure ourselves that there is a knowledge of God in the Scriptures. And, before we do that, we must assure ourselves that there is a knowledge of God in the world. And, before we do that, we must assure ourselves that a knowledge of God is possible for man. And before we do that, we must assure ourselves that there is a God to know. Thus, we inevitably work back to first principles. Selected Shorter Writings, 2:98.
In other words, Warfield is proposing a stepwise proof, in which one thing presupposes another, like a logical syllogism. But even if we grant his methodology, it doesn't follow from this that the order in which you prove something parallels the order of importance.
Suppose we said, the resurrection of Christ presupposes the death of Christ, and the death of Christ presupposes the birth of Christ. Therefore, the Resurrection "is, at the very most, a secondary doctrine."
Likewise, the NT presupposes the OT. Does it follow that the NT is, at best, of secondary importance to the Christian faith?
Even if you use a linear proof, the order in which you prove something is not a ranking system. It's not an argument in descending order of importance, where what is prior is more essential or fundamental than what is posterior in the logical or causal sequence.
vi) Moreover, is Warfield's argument the only proper way to arrive at the conclusion? Must we always begin with first principles?
Take a comparison: when I observe seagulls, I know a large body of water is nearby. Suppose I'm driving to the coast, but I'm lost. If, however, I begin to notice seagulls in the direction I'm driving, whereas there were no seagulls for miles behind, I can reasonable infer than I'm approaching the coast. I'm getting close to the ocean.
But suppose I'm Warfield. Suppose I say:
In proving my proximity to the beach, seagulls are not the first thing I appeal to. For seagulls can't exist unless seagulls come from eggs. And seagulls can't make coastal waters their habitant unless there's an ocean in the first place. Therefore, I must first prove the existence of the sea, then prove that seagulls come from eggs, before I can appeal to sightings of seagulls as evidence for the nearby ocean.
That's clearly backwards. And that's because the order of knowing reverses the order of being.
You don't have to begin with first principles. You don't have to begin with causes. You can begin with effects. The Bible is the effect of divine agency: revelation, inspiration, and historical causation. So it's not illicit to reason back from Scripture, as a starting-point, to its ultimate cause.
vii) How did most Jews and Christians come to believe in the scriptures? Not through Warfield's argument. For Jewish and Christian believers who were raised in the faith, in many cases they can't remember a time when they didn't believe in the God of prophets. Their religious experience is a package.
If, moreover, the God of Scripture exists, then these aren't separable elements in reality, even if they are logically separable. So why demand that we must take it apart and rearrange it in Warfield's schematic fashion?
In fact, Warfield falls back on intuition when he's writing for a popular audience. He knows his methodology won't work for the average layman. Take his essay on the deity of Christ (from The Fundamentals):
A man recognizes on sight the face of his friend, or his own handwriting. Ask him how he knows this face to be that of his friend, or his handwriting to be his own, and he may be dumb [i.e. speechless], or, seeking to reply, may babble nonsense. Yet his recognition rests on solid grounds, though he lacks analytical skill to isolate and state these grounds. We believe in God and freedom and immortality on good grounds, though we may not be able to satisfactorily analyze these grounds. No true conviction exists without adequate rational grounding in evidence. So, if we are solidly assured of the deity of Christ, it will be on adequate grounds, appealing to the reason. But it may well be on grounds not analyzed, perhaps not analyzable, by us, so as to exhibit themselves in the forms of formal logic.
We do not need to wait to analyze the grounds of our convictions before they operate to produce convictions, any more than we need to wait to analyze our food before it nourishes us. The Christian's conviction of the deity of his Lord does not depend for its soundness on the Christian's ability convincingly to state the grounds of his conviction. The evidence he offers for it may be wholly inadequate, while the evidence on which it rests may be absolutely compelling.
